Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a mobile terminal integrating multiple positioning modes. Background Art

[0002] With the rapid development of mobile communication technology, smartphones, as the most common mobile terminals, have become an indispensable part of people's daily lives. In addition to basic call and text messaging functions, smartphones also integrate a variety of advanced functions, among which positioning services are an important function frequently used by users. Positioning services not only play a key role in navigation and map applications, but also have a wide range of applications in social, security and other fields. At present, the mainstream positioning systems include the Global Positioning System (GPS), China's Beidou Satellite Navigation System (BDS), Russia's GLONASS and Europe's Galileo. Each positioning system has its own unique advantages and applicable scenarios. Therefore, mobile terminals that integrate multiple positioning modes can provide users with more accurate and reliable positioning services.

[0003] Currently, most smartphones already support multiple positioning systems, but these devices usually use a single positioning system (such as GPS) by default, or allow users to manually select different positioning systems. This manual switching method has the following problems:

[0004] Users need to manually switch the positioning system, which is cumbersome and easy to forget to switch, affecting the user experience;

[0005] In certain scenarios, a single positioning system may not provide the best positioning accuracy. For example, in densely populated urban areas, GPS signals may be blocked by tall buildings, while the Beidou system has better coverage and service quality in China.

[0006] Enabling multiple positioning systems at the same time will increase the power consumption of the device and affect battery life;

[0007] Therefore, we propose a mobile terminal that can switch automatically and has low power consumption. Summary of the invention

[0008] The object of the present invention is to provide a mobile terminal integrating multiple positioning modes, which can switch automatically and has low power consumption.

[0009] The present invention is achieved through the following technical solutions.

[0010] A mobile terminal integrating multiple positioning modes, including:

[0011] Mobile terminal body,

[0012] A first positioning module is configured in the mobile terminal body and is used to receive and send signals from a first satellite system;

[0013] A second positioning module is configured in the mobile terminal body and is used to receive and send signals from a second satellite system;

[0014] The intelligent switching module is used to automatically switch the operation of the first positioning module and the second positioning module according to the user's usage scenario, the strength of the satellite signal, and the power status of the mobile terminal body.

[0015] Furthermore, the first satellite system is a GPS system.

[0016] Furthermore, the second satellite system is the BeiDou system.

[0017] Furthermore, the software architecture of the second positioning module adopts the 2.0 version binding HAL of the HIDL system.

[0018] Furthermore, the framework and HAL of the HIDL system run in different processes respectively.

[0019] Furthermore, the firmware upgrade of the HAL is in the vendor partition.

[0020] Furthermore, the intelligent switching module includes a data acquisition unit, an identification unit and an automatic switching unit;

[0021] The data collection unit is used to collect the current location information of the mobile terminal, the current time information, and the signal strength information of various satellite systems;

[0022] The identification unit determines the current optimal positioning module based on various information collected by the data collection unit using predefined rules and analysis algorithms;

[0023] The automatic switching unit switches to the first positioning module or the second positioning module according to the judgment result of the identification unit.

[0024] Furthermore, the rules predefined by the identification unit include geographic location rules, time rules and signal strength rules; the geographic location rules are specifically: the Beidou system is given priority in densely populated urban areas in China, the system with the highest signal strength is given priority in remote areas in China, and the GPS system is given priority in other countries or regions;

[0025] The time rules are as follows: from 6:00 to 18:00, the system with higher signal strength is given priority; from 8:00 to 6:00, the system with higher signal stability is given priority;

[0026] The signal strength rule is as follows: if the signal strength of a certain system exceeds a preset threshold, the system is used first; if the signal strengths of multiple systems exceed the threshold, the system with the strongest signal is selected; if the signal strengths of all Russian systems are below the threshold, the system with the most stable signal is selected.

[0027] Furthermore, the predefined analysis algorithm includes priority sorting, weight allocation and comprehensive scoring, wherein priority sorting is used to sort the importance of geographic location rules, time rules and signal strength rules, and assign corresponding weights according to the importance of each rule. Finally, the conditions in the currently satisfied rules and the corresponding weights are combined and calculated to obtain the current optimal positioning module.

[0028] Furthermore, the weights of the geographic location rule, time rule and signal strength rule are respectively

[0029] 0.5, 0.3 and 0.2.

[0030] The technical solution of the present invention has at least the following advantages and beneficial effects:

[0031] The present invention discloses a mobile terminal integrating multiple positioning modes, which can automatically switch positioning modules, thereby making the positioning method of the mobile terminal more diversified, and the switching conditions of the positioning modes are formulated according to the user's usage conditions. Therefore, it can not only meet the user's needs, but also match the current usage scenario, thereby achieving the purpose of reducing power consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1

[0041] Combined with Figure 1 The mobile terminal integrating multiple positioning modes comprises:

[0042] The mobile terminal body 1 is a mobile device capable of receiving satellite signals, such as a satellite phone, a satellite computer, etc.

[0043] A first positioning module 2, configured in the mobile terminal body 1, and used for receiving and sending signals of a first satellite system, wherein the first satellite system is a GPS system;

[0044] A second positioning module 3 is configured in the mobile terminal body 1 and is used to receive and send signals of a second satellite system, wherein the second satellite system is a Beidou system;

[0045] The intelligent switching module 4 is used to automatically switch the operation of the first positioning module 2 and the second positioning module 3 according to the user's usage scenario, the strength of the satellite signal, and the power status of the mobile terminal body 1.

[0046] That is, the mobile terminal has two satellite navigation modes, namely GPS navigation and Beidou navigation. However, the two modes have different received signal strengths depending on the time and space of the mobile terminal. Therefore, the intelligent switching module 4 is used to switch between the two satellite navigation modes, thereby reducing power consumption and ensuring the satellite signal of the mobile terminal.

[0047] In addition, the software architecture of the second positioning module 3 adopts the HIDL system, that is, the 2.0 version of the hardware interface definition language system, the bound hardware abstraction layer HAL, that is, the Binderized mode, which is implemented through the inter-process communication Binder mechanism, so that the framework Framework and the hardware abstraction layer HAL run in different processes respectively, which is similar to the client-server architecture, that is, the framework Framework serves as the client and the hardware abstraction layer HAL serves as the server. Such an architecture reduces the system coupling.

[0048] In addition, by upgrading the HAL firmware in the vendor partition, there is no need to reorganize the system. The vendor partition is an independent partition used to store hardware-related drivers, firmware, HAL implementations, and other vendor-specific components, so the upgrade of the hardware abstraction layer HAL will not affect the operation of the overall system;

[0049] This solution can also ensure that there is no impact on the system power consumption. The power consumption in both satellite navigation modes is as low as possible. In GPS mode, the independent Beidou chip can maintain low power consumption; while in independent Beidou mode, the GPS chip maintains low power consumption, making it easy to switch between the two, instead of restarting the corresponding satellite navigation module when switching.

[0050] Example 2

[0051] Combined with Figure 2 The intelligent switching module 4 includes a data acquisition unit 41, an identification unit 42 and an automatic switching unit 43;

[0052] The data acquisition unit 41 is used to collect the current location information of the mobile terminal, the current time information, and the signal strength information of various satellite systems; and this information basically summarizes the factors that determine the selection of the two navigation modules, so by analyzing the relationship between these factors, it can be determined which navigation module is more suitable for the current scenario, and the selection of a suitable navigation module can stably receive satellite navigation signals with low power consumption, thereby reducing the overall power consumption of the mobile terminal and improving the endurance of the mobile terminal;

[0053] In addition, the location information refers to the current geographical coordinates of the mobile terminal, which are usually expressed in longitude and latitude. When collected, it is obtained by the currently running navigation module. If the navigation function of the mobile terminal is just turned on, it is first obtained by the first navigation module. It should be noted that the location information obtained at this time is approximate location information, so there is no need to consume or consume more energy for precise positioning;

[0054] The time information refers to the current date and time, which is used to analyze the signal strength changes in different time periods. The collection method can directly read the system time of the mobile terminal;

[0055] The signal strength information refers to the current signal strength of each satellite system, which is usually expressed as a signal-to-noise ratio (SNR). The information is collected by the corresponding navigation module of the navigation system.

[0056] The identification unit 42 determines the current optimal positioning module based on the various information collected by the data collection unit 41 using predefined rules and analysis algorithms, wherein the predefined rules are judgment conditions, and the processor of the mobile terminal can determine the current scene of the mobile terminal and the situation of the satellite system according to the collected information and these rules; and the predefined analysis algorithm determines the specific positioning module to be finally selected according to the situation judged by the rules;

[0057] In addition, the rules predefined by the identification unit 42 include geographic location rules, time rules and signal strength rules; the geographic location rules are specifically: the Beidou system is used preferentially in densely populated urban areas in China, the system with the highest signal strength is used preferentially in remote areas in China, and the GPS system is used preferentially in other countries or regions;

[0058] The time rules are as follows: from 6:00 to 18:00, the system with higher signal strength is given priority; from 8:00 to 6:00, the system with higher signal stability is given priority;

[0059] The signal strength rule is specifically as follows: if the signal strength of a system exceeds a preset threshold, the system is used first; if the signal strengths of multiple systems exceed the threshold, the system with the strongest signal is selected; if the signal strengths of all systems are below the threshold, the system with the most stable signal is selected.

[0060] According to the needs, the predefined analysis algorithm includes priority sorting, weight allocation and comprehensive scoring, wherein the priority sorting is used to sort the importance of geographic location rules, time rules and signal strength rules, and assign corresponding weights according to the importance of each rule, and finally combine the conditions in the currently satisfied rules and the corresponding weights and calculate to obtain the current optimal positioning module;

[0061] In addition, the specific steps of the analysis algorithm are:

[0062] S1. Collect the current geographic location, signal strength, time and other information in real time to construct a feature vector, namely:

[0063] X currcnt =(snr BDS ,snr GPS ,city flag ,day flag )

[0064] S2. Substitute the feature vector into the geographic location rule, time rule and signal strength rule in sequence to obtain the corresponding result;

[0065] S3. According to the result of S2, the weight assignment of each rule is combined and a comprehensive calculation is performed to obtain the current optimal positioning module, where the comprehensive calculation formula is:

[0066] Comprehensive score = geographic location weight × geographic location score + time weight × time score + signal strength weight × signal strength score.

[0067] In particular, the weights of the geographic location rule, time rule and signal strength rule are respectively

[0068] 0.5, 0.3 and 0.2;

[0069] Take this weight distribution as an example, and in the daytime, in the urban area of ​​China, at the same time, the signal strength SNR of the Beidou system is 35dB, and the signal strength SNR of the GPS system is 30dB; and the signal of the GPS system is more stable;

[0070] Then, according to the geographical location rule, the BeiDou system will be given priority;

[0071] According to the time rule, the system with the highest signal strength, namely the BeiDou system, will be given priority;

[0072] According to the signal strength rule, the signal strength of the Beidou system exceeds the specified threshold of 30dB, and the signal strength of the GPS system is equal to the specified threshold of 30dB;

[0073] The comprehensive rating is:

[0074] 1. BeiDou system:

[0075] Location score: 1

[0076] Time score: 1

[0077] Signal strength score: 10

[0078] Comprehensive score: 0.5*1+0.3*1+0.2*10=3.8

[0079] 2.GPS system:

[0080] Geographical score: 0

[0081] Time score: 0

[0082] Signal strength score: 9

[0083] Comprehensive score: 0.5*0+0.3*0+0.2*9=1.8

[0084] The system with the highest comprehensive score is the BeiDou system (3.8 points), so the first positioning module 2 is selected as the optimal positioning module.

[0085] The automatic switching unit 43 switches to the first positioning module 2 or the second positioning module 3 according to the determination result of the identification unit 42 .

[0086] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
